This adds a quick sanity check to the `cluster init` command to verify that the Config object is valid prior to running the command. Note: This check is repeated later on when the command calls CurrentContextTargetPath, but that check is being removed in a separate change. Closes: #214 Change-Id: I405dbcf2df068f7f3aa008454f92620063de9d9e
